Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces HY/T 074-2003 "Design Specification for Membrane Water Treatment Reverse Osmosis Seawater Desalination Project". This standard and Compared with HY/T 074-2003, the main technical changes are as follows. --- The standard name was changed to "Design Specification for Reverse Osmosis Seawater Desalination Project"; --- The standard scope was revised to "Applicable to the design of seawater desalination projects for new construction, expansion and reconstruction of 100m3/d and above"; --- According to the needs of the standard documents, some normative references are deleted and supplemented; --- Delete the.2003 version of the term and definition "3.3 composite film", "3.6 recovery rate" was changed to "water recovery rate"; --- "4 Master Plan" was revised to "4 Overall Design", adding general rules, water production, water quality, land area, plane and elevation Design, pipeline design, production room, sewage treatment, plant design, etc.; --- "5 seawater water intake" increased "5.1 general provisions", the.2003 version of "5.1 seawater water intake site selection" was revised to "5.2 sea "Selection of water source and water intake location", "5.2 Seawater water intake method" was changed to "5.3 Seawater water intake structure", "5.3 Seawater The pumping station was revised to “5.4 seawater pump and pump room”, and the relevant contents of each section were revised and supplemented; ---Modified and supplemented the "6 seawater pretreatment" content, deleted the.2003 version of the "6.1 general requirements" cellulose acetate roll Membrane element and hollow fiber reverse osmosis membrane module inlet water quality index requirements, part of the influent water for reverse osmosis desalination membrane unit The quality index requirements have been adjusted, and the pre-treated seawater CODMn content index has been removed, and the water temperature has been increased (2°C~40°C). The indicator changed the water quality pH range (3~10); deleted the design content of the advection sedimentation tank, chemical regulation and security filtration, etc. Added floating sedimentation tank and super (micro) membrane filtration pretreatment process design and other related content; ---2003 edition "7 reverse osmosis seawater desalination treatment" was changed to "7 reverse osmosis seawater desalination system", desalination according to reverse osmosis seawater The main components of the system and subsystems, respectively, for security filters, high-pressure pumps, reverse osmosis membrane devices, energy recovery devices, The design of cleaning and rinsing devices is specified..2003 edition "8 high pressure pump and energy recovery unit" and "9 cleaning equipment The contents of the "" are incorporated into the revised "7 reverse osmosis seawater desalination system", and the relevant content has been modified and supplemented; --- Added "8 water treatment agent dosage" to stipulate the process design of each dosing link of reverse osmosis seawater desalination project; ---2003 edition "11 Concentrated water discharge and post-production water treatment" was revised and divided into "9 reverse osmosis post-treatment" and "10 discharge" "Water treatment" two chapters, and added some design content; --- The.2003 version of the "10 pool" was changed to "11 tanks", and the relevant design of the tank was supplemented; --- Modified and supplemented the "12 Control and Instrumentation" and "13 Power Distribution" design related content.

1 Scope

This standard specifies the general principles and methods for the design of seawater desalination projects with reverse osmosis technology as the core. This standard is applicable to the design of reverse osmosis desalination projects for new construction, expansion and reconstruction of water production capacity of 100m3/d and above. Scale seawater and high salinity brackish water (soluble total solids ≥ 10000mg/L) desalination engineering design can be used.
